Hey guys, i purchased a denon 1911 recently. I currently have my samsung plasma hooked to the receiver via hdmi out, PS3 hooked to BD hdmi in and a xbox 360 hooked to the DVD hdmi in. When i select BD the ps3 works fine on a/v output. When i select DVD my xbox produces no sound or video. Anyone have an idea why this is happening? Any input will be greatly appreciated, thanks.
